Update:
okay, so here's the story. I bought a new computer (a display model

) for a really good deal, but the store had to reset windows. When I took it home, I started to un-install all of the fluff on it, and put my stuff on it.
When I got to AVG, I went to reboot it after the install, and windows wouldn't start.

It wouldn't start in safe mode, nuttin! So I made a recovery disk off our other windows 7 comp, but it is 32 bit and didn't work, but I could atleast semi-access the repair screen. I'd run repair mode, and windows said there was nothing wrong

. I called AVG, and they said it was a windows problem, re-install windows

.
So, by 2 am, I gave up and decided to have the store tech dept look at it. (basically re-install windows- The comp didn't come with a windows disk

)
The tech guy, started it up, went through the song and dance, then threw his arms up in the air and said "there's nothing I can do, we need to send it to the vendor." So I just returned the computer and got a refund.
Round two:
So I got a different computer, took it home and made a back-up disk

first thing. Un-installed mcafee, installed AVG, and I got an error message this time: "the AVG intaller program was corrupt(?) and I needed to use the online installer. So I did that, and no problems, everything works.
